When you lose weight, how does the fat leave the body….

Question

I’ve heard you literally poo and wee it out

In: Biology

Answer 1

In this specific context, think of your body like a fireplace and chimney.

The fat is wood. Your metabolism is the fire. The fat burns and leaves behind smoke (the byproducts). That smoke exits through your lungs and out your nose/mouth (all together, the chimney).

This is oversimplified, but a good way to picture it.
